SPECIFICATION forming part of Letters Patent No. 642,946, dated February 6, 1900.

Application filed May 20, 1899- Serial No. 717,594. (No model.)

To all whom it may concern:

Beit known that I, HoRAoE WYMAN, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Looms, of which the following is a specification.

My invention relates to looms, and more particularly to improvements in automatic shuttle-changing looms of the class shown'and described in United States Patent No. 614, 369.

The object of my invention is to provide improved devices to-be combined with and applied to automatic shuttle-changing looms of the class above referred to, and particularly to said patented loom, to prevent the lay from banging against the stopping-bunters when the spare shuttle fails to be supplied from the shuttle-feeder mechanism for any reason, as is common in looms when there is no shuttle at either end of the lay.

In my improvements if the filling of the running shuttle indicates changing shuttles and the operation of the change-shuttle mechanism and there is no spare shuttle on the plate of the shuttle-feeder the first part of the movement of the shuttle feeder will, through intermediate connections,operate the knock-off lever and move the shipper-lever to stop the loom before the lay can strike against the stopping-hunters.

My invention consists in certain novel features of construction and operation of mechanism for stopping the loom if there is no shuttle on the shuttle-feeder, as will be hereinafter fully described.

I have shown in the drawings myimprovements combined with the shuttle-changing mechanism shown and described in said Patent No. 614,369; but I do not limit myinvention to this particular shuttle-changing mechanism, as my improvements may be combined with other shuttle-changing mechanisms, if desired.

I have shown in the drawings only such parts of a loom and said patented shuttlechanging mechanism with my improvements combined therewith as will be necessary to enable those skilled in the art to which my invention relates to make and use the same.

Referring to the drawings, Figure 1 is an end view of a portion of a loom, looking in the direction of arrow a,'Fig. 2, showing some of the parts of the shuttle-changing mechanism shown in said Patent No. 614,369 and also showing my improvements combined therewith sufficient to illustrate the operation thereof. Fig. 2 is a rear view taken at a point indicated by line 2 2, Fig. 1, looking and described in said Patent No. 614,369.

The lever 3 is centrally pivoted at eland has the upper end of a rod or link 5 adjustably connected with one slotted end thereof. The lower end of the link 5 connects with a pin on a disk, (not shown,) through which rocking motion is communicated to the lever 3, as

fullydescribed in said patent. The opposite end of the lever 3 has adjustably attached to the slotted end thereof the upper end of a rod or link 6, the lower end of which is attached to the block 7, to which is attached the lower end of the shuttle-box rod 8, to raise and lower said rod, as fully described in said patent.

The lever or bar 9 of the shuttle-feeder is pivoted at its lower on a stud l0 and carries at its upper end the plate 11, on which is supported the spare shuttle 12, as described in said patent. V

The lever or bar 9 is forked or divided at its upper end, as shown in Fig. 2, and carries a roll 9, which as the lever 9 is lifted with the box-rod 8 by the lever 3 acts against the under inclined side of the finger 13, Fig. 1,

and causes the shuttle-feeder plate 11, carry- 5 automatically operate theknock-off lever and move the shipper-lever to stop the loom in case there is no shuttle on the shuttle-feeder.

A stand or bracket 11 is secured to the inside of the breast-beam 2 at the shuttle'feedermechanism end of the loom. On a stud in the upper part of said stand 14 is pivotally supported an angle-lever 15. 'loone end of the angle-lever 15 is pivotally connected the upper end of a lever 16. A spring 17, extending in a recess in the lever 16 and in the angle-lever 15, acts to move the lever 16 outwardly, as shown in Fig. 1. The lower end of the lever 16 extends through a slot or opening in an extension 14 on the stand 14, and said lever 16 has an offset or side projection 16, with alip or extension 16" thereon, which in case the lever 16 is not held in its inward position (shown in Fig. 2) by the end of the shuttle 12 engaging therewith will extend over an extension 11 on the plate 11 of the shuttle-feeder mechanism, as shown in Fig. 4. The other arm of the angle-lever 15 has pivotally connected thereto one end of a rod or connector 18. The other endof the rod or connector 18 is pivotally connected to one arm of an angle-lever 19, pivoted on a stud 20. The other arm of said angle-lever 19 rests at 21 on the end of the knock-off lever 21, fast on a rocloshaft 22, mounted in bearings at the front of the breast-beam, and the upwardlyextending arm 21 of the knock-oif lever 21 engages the shipper-lever23, as shown in Fig. 3, to unlock said lever 23 and stop the loom in the ordinary way.

Referring to Figs. 2 and 4, it will be seen that when there is a shuttle on the plate 11 of the shuttle-feeder mechanism the lever 16 will be engaged by said shuttle, as shown in Fig. 2, and held in such a position that the movement of the shuttle-feeder plate 11 to supply a new shuttle to the loom in case of the failure of the filling in the running shuttle will not engage said lever 16 to operate through intermediate connections the knockoff lever and shipper-lever and stop the loom; but in case there is no shuttle on the plate 11 of the shuttle-feeder mechanism then the lever 16 will be moved outwardly by the spring 17, as shown in Fig. 4, so that the lip 16 thereon will extend over and be engaged by the extension 11' on the plate 11 of the shuttle-feeder mechanism if the running shuttle indicates for the operation of the shuttlechanging mechanism in the manner fully described in said Patent No. 614,369, and the movement of the shuttle-feeder mechanism and the raising of the plate 11 will operate,

shuttle-changing mechanism when the operator is placing a new shuttle on the plate 11 of the shuttle-feeder mechanism and injury to the operator from the raising of the plate 11, which might happen, I provide supplemental mechanism consisting of a lever 24, pivoted at 25 on the bracket or stand 1 1 and having at its lower end a pin 25, which engages the inclined end 26 of a lever 26, pivotally supported on a pin 27, extending in the lower slotted end of the stand 1 1-. The opposite end of the lever 26 is provided with a lip or extension 26", which extends under an arm or rod 28, secured on the end of the rod 29, connected to the elbow-lever 30,forminga part of the shuttle-changing mechanism shown and described in said PatentNo. 614,369. The end of the lever 28 extends through a slot in the lower end of the arm 31, fast on the rockshaft 22, and a lip 28 on said arm 28 engages with the arm 31 when the lever 28 is in its lower position, as shown in Fig. 1. When the arm 28 is raised by the movement of the lever 26, caused by the movement to the left of the lever 2-1 by the operator, as shown in Fig. at, the lip 28on said arm 28 will not be engaged by the slotted end of the arm 31, fast on the rock-shaft 22, so that the rocking of said shaft by the filling-fork motion and the movement of the arm 30 will not move the arm 28 to put into operation the change-shuttle mechanism, as described in said Patent No. 614,369. After a shuttle has been placed on the plate 11 of the shuttle-feeder mechanism the lever 21 is moved to the right by the operator, as shown in Fig. 2, to allow the end of the lever 26 to drop down, and with it the arm 28, into the position shown in Fig. 1, ready to be engaged and operated by the arm 31 on the rock-shaft 22.

It will be understood that the details of construction of my improvements may be varied, if desired, and they may be adapted to be applied to different styles of change-shuttle looms.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a loom of the class described, the combination with the shuttle-bearing plate of the sh little-feeder mechanism, for the extra shuttle, and the knock-off lever and shipper, of intermediate connections operated by the shuttle-bearing plate to operate the shipper and stop the loom when a shuttle is absent from the shuttle-bearing plate, substantially as shown and described.

2. In a loom of the class described, the combination with the shuttle-bearing plate of the shu ttlefeeder mechanism, for the extra shuttle, and the knock-off lever and shipper, of intermediate connections, comprising an angle-lever, a lever connected with one arm thereof and engaged by the shuttle when the shuttle is on the plate of the shuttle-feeder mechanism, and in the absence of the shuttle engaged by the shuttle-plate of the shuttlefeeder mechanism, a connector attached to the other arm of said angle-lever, a second angle-lever, one arm connected With said connector, and the other arm adapted to engage the knock-off lever, to operate the same and move the shipper-lever to stop the loom, substantially as shown and described.

3. In a loom of the class described, the combination with the sh uttle-bearing plate of the shuttle-feed mechanism for the extra shuttle, the knock-off lever and shipper, and intermediate connections, of a movable lever with a projecting part in the path of movement of the shuttle-bearing plate, said lever, through intermediate connections, being adapted to operate the shipper and stop the loom When scribed.
